Use valid ronn syntax in filebucket help

Previously, running `rake manpages` resulted in:

     roff: ./man/man8/puppet-filebucket.8
     warn: unrecognized block tag: "blockquote"

This is because '>' is not valid ronn syntax. As a result the "Note" was
excluded from the generated `man/man8/puppet-filebucket.8`

Also add a new line to separate using a local filebucket.
